Muaj Ntau Lawm Ntawm Bleaching Powder Thiab Bleaching Powder Concentrate Project

Ntau tus neeg Esxias sab hnub tuaj tau ntsib teeb meem ntawm kev tsim cov tshuaj bleach ntau thiab cov tshuaj bleach concentrate. Lawv tau sim ntau txoj hauv kev, tab sis cov txiaj ntsig tsis zoo. Rau qhov no, lawv tau hu rau peb, ACHIEVE CHEM, vam tias peb tuaj yeem muab kev daws teeb meem zoo. Raws li lub tuam txhab ua lag luam tshuaj lom neeg ntau lawm, peb tsis ntev los no tau muaj cai koom nrog hauv ib txoj haujlwm tseem ceeb hauv kev tsim cov hmoov bleaching thiab bleaching hmoov concentrate. Cov phiaj xwm no qhia peb cov txiaj ntsig hauv kev muab cov neeg siv khoom nrog cov kev daws teeb meem.

Ob qho tshuaj sib npaug rau kev lag luam tsim cov tshuaj dawb thiab tshuaj dawb cov hmoov concentrate:

1. 2 Ca (OH) 2+2Cl2=Ca (ClO) 2+CaCl2+2H2O

Qhov no yog ib qho kev sib npaug ntawm cov tshuaj chlorine gas nrog calcium hydroxide (tseem hu ua hydrated txiv qaub), siv los npaj cov hmoov bleaching. Hauv cov tshuaj tiv thaiv no, chlorine gas reacts nrog calcium hydroxide los tsim calcium hypochlorite (Ca (ClO) 2), calcium chloride (CaCl2), thiab dej.

Lub tshuab ntawm cov tshuaj tiv thaiv no yog tias cov roj chlorine ua ntej yaj hauv dej, tsim cov hydrochloric acid thiab hypochlorite ions (ClO -). Tom qab ntawd, hypochlorite ion reacts nrog calcium hydroxide los tsim calcium hypochlorite thiab dej. Calcium hypochlorite yog cov tshuaj oxidizing heev uas tuaj yeem siv rau tshuaj dawb thiab tshuaj tua kab mob.

2. 2NaOH+Cl2=NaCl+NaClO+H2O

Qhov kev sib npaug no kuj yog siv los npaj cov tshuaj dawb. Hauv cov tshuaj tiv thaiv no, chlorine gas reacts nrog sodium hydroxide los tsim sodium chloride (NaCl), sodium hypochlorite (NaClO), thiab dej.

Lub tshuab ntawm cov tshuaj tiv thaiv no zoo ib yam li thawj cov tshuaj tiv thaiv. Chlorine yog thawj yaj hauv dej, tsim hydrochloric acid thiab hypochlorite ions (ClO -). Tom qab ntawd, hypochlorite ion reacts nrog sodium hydroxide los tsim sodium hypochlorite thiab dej. Sodium hypochlorite kuj yog ib yam khoom uas muaj oxidizing heev uas yuav siv tau rau bleaching thiab tshuaj tua kab mob.

Nws yuav tsum tau muab sau tseg tias ob qho tib si tshuaj tiv thaiv yuav tsum tau ua raws li tej yam kev mob. Piv txwv li, qhuav calcium hydroxide los yog sodium hydroxide tsis tuaj yeem hnov ​​​​mob nrog cov roj chlorine, vim cov roj chlorine tuaj yeem tsuas yog adsorbed los ntawm cov tshuaj no. Tsis tas li ntawd, cov tshuaj tiv thaiv no yuav tsum tau ua nyob rau hauv qhov tshwj xeeb kub thiab siab siab los tswj cov tshuaj tiv thaiv tus nqi thiab cov khoom zoo.

Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm ob qhov kev cuam tshuam:

1. 2 Ca (OH) 2+2Cl2=Ca (ClO) 2+CaCl2+2H2O:

* Qhov zoo: Cov khoom siv raw yog los ntawm ntau qhov chaw thiab yooj yim los tuav, thiab cov txheej txheem tshuaj tiv thaiv kuj yooj yim.

* Qhov tsis zoo: Cov khoom tsim calcium hypochlorite thiab calcium chloride tuaj yeem muaj kev sib cais nyuaj thiab xav tau kev kho mob ntxiv.

2. 2NaOH+Cl2=NaCl+NaClO+H2O:

* Qhov zoo: Cov khoom tsim sodium hypochlorite muaj oxidation tsis kam thiab tuaj yeem siv rau hauv ntau daim ntawv thov.

* Qhov tsis zoo: Raw chlorine roj yuav ua rau muaj kev phom sij thiab yuav tsum muaj kev tuav thiab khaws cia.

Los ntawm kev sib piv cov txiaj ntsig thiab kev ua tau zoo ntawm ob qhov kev tshwm sim, Scheme 1 muaj qhov zoo ntawm ntau yam khoom siv raw thiab cov txheej txheem tshuaj tiv thaiv yooj yim, tab sis cov khoom sib cais yuav xav tau kev ua haujlwm ntxiv. Txawm hais tias Scheme 2 siv cov khoom siv phom sij chlorine gas, nws cov khoom muaj oxidation tsis kam thiab muaj ntau yam kev siv. Yog tias koj xav tau cov txheej txheem tshuaj tiv thaiv yooj yim dua thiab nyab xeeb dua, koj tuaj yeem xaiv Scheme 1; Yog xav tau cov khoom oxidizing siab, Scheme 2 tuaj yeem xaiv.

Cov lus qhia thiab kev tshuaj xyuas rau kev yuav khoom siv tshuaj:

Muaj ntau yam khoom siv tshuaj reactor tsim nyog, txhua tus muaj nws tus yam ntxwv, suav nrog iav, stainless hlau, iav hauv ob sab phlu, thiab lwm yam.

1. iav reactor: Tus nqi qis, nrog zoo heev corrosion kuj, pob tshab, thiab kub tsis kam, dav siv nyob rau hauv kev lag luam xws li chaw soj nstuam, tshuaj, thiab tshuaj. Tab sis lub zog yog tsawg thiab yooj yim tawg.

2. Stainless hlau tshuaj tiv thaiv kettle: Tus nqi pheej yig, nrog zoo corrosion kuj, kub tsis kam, thiab siab zog, dav siv hauv kev lag luam xws li tshuaj, tshuaj, thiab khoom noj.

3. Iav lined tshuaj tiv thaiv kettle: Nqis, nrog zoo heev corrosion thiab kub tsis kam, haum rau ntau yam tshuaj tiv thaiv. Tab sis nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov kub thiab txias txwv thaum siv.

4. Carbon steel tshuaj tiv thaiv kettle: Tus nqi qis, tsim nyog rau ntau yam tshuaj tiv thaiv, tab sis yuav tsum tau them nyiaj rau kev tiv thaiv corrosion thiab tu tsis tu ncua.

Rau ob txoj kev daws teeb meem saum toj no, ACHIEVE CHEM xav kom cov neeg siv khoom xaiv cov kev daws teeb meem tsim nyog raws li lawv qhov xwm txheej tiag tiag. Nyob rau tib lub sijhawm, peb kuj tau muab cov lus qhia thiab kev tshuaj xyuas ntawm cov khoom siv tshuaj lom neeg uas yuav siv tau. Rau Scheme 1, peb pom zoo kom siv cov evaporator teb kom mloog zoo rau cov tshuaj tiv thaiv, thiab tom qab ntawd siv lub centrifuge rau cov kua-kua sib cais. Rau Scheme 2, peb xav kom siv ib qho kev txhaj tshuaj los yog tov khoom rau cov tshuaj tiv thaiv, thiab tom qab ntawd siv lub lim xovxwm rau cov kua dej sib cais. Nyob rau hauv cov nqe lus ntawm kev xaiv cov cuab yeej, peb hais txog qhov corrosion kuj thiab stability ntawm cov cuab yeej los hloov mus rau tej yam corrosive ib puag ncig. Nyob rau tib lub sijhawm, peb kuj tau txiav txim siab qhov ua tau zoo thiab yooj yim ntawm kev siv cov cuab yeej ua kom tau raws li qhov xav tau ntawm cov khoom loj.

Kev ua tiav thiab kev ua tau zoo ntawm qhov project

Tom qab kev sib tham tob thiab kev koom tes nrog peb cov neeg siv khoom, peb txoj kev npaj tau ua tiav thaum kawg. Cov neeg siv khoom tau lees paub peb cov kev daws teeb meem thiab ua tsaug rau peb cov kev paub dhau los thiab kev txhawb nqa. Qhov kev vam meej ntawm txoj haujlwm no tsis yog tsuas yog daws cov teeb meem siv tau rau peb cov neeg siv khoom xwb, tab sis kuj tseem txhawb nqa peb ACHIEVE CHEM txoj haujlwm tseem ceeb hauv kev tsim khoom siv tshuaj lom neeg. Peb ntseeg ruaj khov tias tsuas yog los ntawm kev daws teeb meem cov neeg siv khoom tiag tiag tuaj yeem paub peb tus nqi.
